‘Original Sin’ in Latin America (2000-2015): Theory, Empirical Assessment and Alternatives
Ettore Gallo, Maria Cristina Barbieri Góes e Vinícius Diniz Moraes*
Abstract: The matter of the ‘original sin’, the inability to borrow abroad in domestic currency, came to the centre of the academic discussion after the dramatic episodes in Asia, Russia and Latin America. According to this international framework, this paper is an empirical analysis of ‘original sin’ for six Latin American countries based on the index (OSIN3) developed by Haussmann and Panizza (2003). This paper finds that the situation for some countries have been improving reflecting a reduction of the index. This fact could be related to recent economic policies related to an ‘abstinence’ rather than ‘redemption’, an attitude seen as a response to the debt crisis. Finally, the paper focuses on possible policy alternatives that could be adopted to overcome the ‘original sin’ phenomenon it includes North-South and South-South cooperation and a multilateral arrangement. However, such alternatives are limited to feasibility mainly due to the turbulent political and economic scenario in the region.

1. Introduction The matter of the ‘original sin’ came to the centre of the academic discussion after the dramatic episodes in Asia, Russia and Latin America (Mexican crisis in 1994, the Asian crisis in 1997, the Russian crisis in 1998, the Brazilian crisis in 1999, the Argentinean crisis in 2002), when the depreciation of local currency together with the denomination of debt in foreign currency – the dollar – resulted in currency, banking and financial crisis. In this context, Eichengreen and Hausmann (1999) define ‘original sin’ as the “inability to borrow abroad in terms of domestic currency and to borrow domestically long-term”. That implies, as stated by Panizza (2006), that ‘original sin’ is a two-dimensional phenomenon, characterized by an international component (the local currency of countries affected by ‘original sin’ cannot be used to borrow abroad) and by a domestic component (the local currency is not used domestically for long-term borrowing).In this sense and in line with the literature, we acknowledge that the need of obtaining foreign exchange reserves is intrinsically related with internal productive structures of countries suffering from original sin. However, we decide to stress solely effects and strategies needed to deal with the external borrowing constraint in a short term analysis. Accordingly, we focus on the international component of ‘original sin’ and how it affected economic stability and borrowing conditions of Latin American countries. According to this international framework, our empirical analysis is based on the index (OSIN3) developed by Haussmann and Panizza (2003). The index will be calculated for Argentina, Brazil, Chile, Colombia, Mexico, Venezuela; later, we will analyse how the data fit the ‘original sin hypothesis’ throughout the time framework chosen (2000-2015). Our approach will, therefore, be based on a theoretical discussion of the phenomenon, by reviewing the academic literature, and a data analysis of ‘original sin’ in six relevant Latin American countries; in particular, we chose them because of their economic prominence in the area (Argentina and Brazil) and their different political peculiarities (Chile, Colombia, Mexico and Venezuela). Regarding the Latin American context, our first research goal is to analyse to what extent the Index (OSIN3) dynamics emphasize the ‘original sin’ and whether these dynamics shows signs of ‘redemption’ in the terms of Eichengreen, Hausmann and Panizza (2002). Secondly, we will focus on how the phenomenon

could be overcome through the alternatives presented in the literature, assessing them and taking into account the current Latin American scenario. We suppose that, in line with the literature, there might have been improvements in the country group analysed in terms of reduction of the index. Nevertheless, this reduction may have been mainly related to an ‘abstinence’ response to a crisis aftermath rather than ‘redemption’. The literature points some alternatives to reach ‘redemption’ including North-South and South-South cooperation and a multilateral arrangement. However, we argue that the feasibility of them is rather complex, especially considering the turbulent state of affairs, both economic and political in the developed and developing world. In Section 2, we deal with ‘original sin’ from a theoretical perspective, reviewing the effects on economic stability and analysing possible causes underlying the phenomenon. In Section 3, we deal with an empirical exercise, analysing a group of Latin American countries, namely Argentina, Brazil, Chile, Colombia, Mexico and Venezuela (2000-2015). In the fourth section, we will present the alternatives able to overcome the phenomenon discussed and assess them under a critical perspective. Finally, we will conclude, summarizing our findings.
2. Theoretical background: ‘Original Sin’ 2.1 What is ‘Original Sin’? As originally defined in Eichengreen and Hausmann (1999), ‘original sin’ is the “inability to borrow abroad in terms of domestic currency and to borrow domestically long-term”. That implies, as stated by Panizza (2006), that ‘original sin’ is a two-dimensional phenomenon, characterized by: - an international component: the local currency of countries affected by original sin cannot be used to borrow abroad. As a consequence, foreign debt will be mainly denominated in foreign currency, generating currency mismatches for countries that are net debtor; - a domestic component: the local currency is not used domestically for long-term borrowing (i.e., local private borrowers prefer to denominate their liabilities in more stable currencies in order to hedge the risk of currency

depreciation). Consequently, maturities in domestic currency can be only either of short or medium term. Eichengreen, Hausmann and Panizza (2002) demonstrated as the ‘original sin’ is a widespread phenomenon, that affects “almost all countries aside from the issuers of the 5 major currencies – the US dollar, the euro, the yen, the pound sterling and the Swiss franc”2. The original sin hypothesis was first developed in order to explain the problems that most developing countries face in borrowing in international capital markets (ICMs henceforth). Therefore, the focus on external debt (the international component of original sin) tries to describe the distortions that affect the flows of capital from capital-rich advanced countries to capital-poor developing countries (EICHENGREEN; HAUSMANN; PANIZZA, 2007)3. As a tool to explain development problems and dependence relations, the theory of international original sin shows as the deficiencies in borrowing in ICMs undermine the possibility for developing countries to stabilize the domestic economy when faced with shocks.
2.2 ‘Internacional Original Sin’ as a threat to economic stability The balance sheet of countries suffering from original sin will be characterized by liabilities mainly denominated in foreign currency. If the country is a net debtor, it will then face a currency mismatch on the balance sheet; in this case, movements in the real exchange rate will generate wealth effects that may lead to higher volatility of output and capital flows, lower credit ratings and less effective monetary policies (EICHENGREEN; HAUSMANN; PANIZZA, 2002). All these factors undermine the domestic economic stability of countries affected by original sin, thus posing a threat to economic growth and development. As summarized in Fritz and Metzger (2006), the relation between ‘original sin’ and
2 Nowadays, the international monetary system is a “non-order” (BIBOW, 2008) characterized by a declining importance of British Pound (in particular after Brexit), as well as of Swiss Franc and Japanese Yen. While China’s renminbi has officially become a reserve currency (joining the IMF’s special drawing rights basket the 1 October 2016), US dollar is losing its unopposed hegemony in the international monetary system. If China will proceed on the path of capital account liberalization, a tripartite World scenario is likely to take shape, where reserves will be denominated into three main currencies: US dollar, Euro and Renminbi. Further discussion can be found in Bergstern (2014), Campanella (2014) and Kruger (2016). 3 Critical remarks about the conventional idea that capital flows from advanced to developing countries are provided by the famous “Lucas Paradox (LUCAS, 1990) and the allocation puzzle (GOURINCHAS JEANNE, 2013).

increasing economic volatility is due to three main reasons, namely currency mismatch, restricted lender-of-last-resort function and costs of original sin in terms of output reduction and uncertainty. First and foremost, the currency mismatch implies that any devaluation of the domestic currency would cause an increase in the real value of foreign debt stock, making more difficult its service. In this scenario, negative expectations on future repayments would create feedbacks resulting in capital flights, thus generating a spiral of worsening expectations and new capital flights. In other words, the capital outflows would behave in a pro-cyclical way, constituting a “loose cannon” for monetary authorities and their space to react. According to Panizza (2006), there are two ways to avoid the mismatches: i. Preventing foreign borrowing (both public and private); in other words, a country can overcome original sin following the extreme decision not to accumulate foreign debt4. ii. Accumulating foreign reserves matching the foreign debt. This solution seems to be the preferred for most countries suffering from original sin: Eichengreen, Hausmann and Panizza (2003a) demonstrated indeed that these countries tend to accumulate more foreign reserves than countries not affected by the phenomenon. Nevertheless, Panizza argues that both measures are costly. On the one hand, in situations of financial autarky countries are unable to overcome or to alleviate shocks through international borrowing; in other words, abdicating or preventing foreign borrowing would mean abdicating additional investment finance and consumption smoothing through international financial integration. On the other hand, an increase in the accumulation of foreign reserves would imply an increasing negative spread between lower yield on reserves and the opportunity costs of funds5. This has been exactly the case in the recent years (especially from
4 As stated by Eichengreen, Hausmann and Panizza (2003a, p. 2): “A financially autarchic country will have no currency mismatch because it has no external debt, even though it still suffers from original sin as we define it”. 5 In this regard it is important to highlight the emergence of a quasi-fiscal deficit. For instance, let us consider the case of Brazil. Since the accumulation of foreign reserves is performed through open market operations, rising bonds yields (attached to the Selic) are required in order to make government bonds accepted in the markets. In doing so, the government is committed to pay a high interest on bonds in order to obtain foreign reserves that it then holds on US American bonds with a lower yield. The spread between the yields paid on national short-term bonds and on the bonds in which the reserves are held creates what is called quasi-fiscal deficit.

the beginning of the 2000’s until the outbreak of the financial crisis) when the countries adopted such measures as a response to the turbulence of the 1990’s. Second, the function of “lender-of-last-resort” would be restricted. Considering the case of banks having liabilities in foreign currency, the Central Bank cannot supply liquidity to the domestic financial sector, since the country does not issue the currency that the debt is denominated in. In this case, the higher the ‘original sin’, the greater the liquidity risk that the financial sector is exposed to. Third, the short and long run costs of the ‘original sin’. In the short run the costs of the ‘original sin’ could be related to the costs of the currency mismatch and in the long run, it would be creating both uncertainty and reduction of output as feedback of the volatility itself. In Section 4, we discuss more in detail what are possible solutions to stabilize Latin American economies affected by ‘international original sin’.
2.3 At the roof of ‘Original Sin’: main causes As argued in Eichengreen, Hausmann and Panizza (2003b) – and schematized by Panizza (2006) in the Table 1 reproduced here – there are six main causes that can explain the existence of ‘original sin’: economic development and institutional quality6, lack of monetary credibility, weak fiscal position, trade links, political economy and international causes linked with country size. Eichengreen et al. (2003b) conducted a multiple regression analysis to evaluate the correlation between these six explanatory variables and three different independent variables, namely three different indicators of original sin; in this paragraph, we focus on the significance of each determinant in respect of OSIN3, the measure that best indicates the international component of ‘original sin’7.
6 The most common indicator to measure economic development is GDP per capita. However, the choice of the indicator in not uncontroversial. Accordingly, an early critique of the idea that economic development can be expressed in terms of GDP per capita can be found in Sen (1988). More generally, as shown by the literature on original sin, institutions matter. In this sense, Panizza (2006, p. 31) stresses that “original sin is merely miner’s canary, signalling the presence of weak institutions and low level of development”. In this sense, an alternative measure of institutional weakness for countries suffering from original sin could be the five-dimensions Institutional Quality Index (IQI) proposed by Nifo and Vecchione (2015), encompassing regulatory quality, government effectiveness, rule of law, corruption, voice and accountability. 7 We will come back on this way to measure ‘original sin’ in Section 3.

Contrary to what might be expected, the analysis showed that there is no significant correlation between ‘original sin’ and the level of economic development; the explanatory variable, expressed in log of per capita GDP, results slightly significant by dropping the regional dummies in the regression, but the result is not robust when we try to make inference on the correlation between original sin and economic development within country groups. The absence of a robust correlation between ‘original sin’ and the level of development implies that other determinants linked with specific countries characteristics are also unlikely to explain the phenomenon; the regression analysis confirms this intuition, demonstrating a weak or absent correlation between OSIN3 and trade links, characteristics of the domestic financial system, monetary credibility and fiscal policy-making. These results are of crucial importance because they contradict the common idea according to which inabilities and difficulties to borrow in ICMs of developing countries are a result of bad policies; in other words, credible monetary and fiscal policies cannot overcome a problem that is linked more closely with international causes.

The authors demonstrated that the only significant variable is the country size: regression analysis shows indeed a strong negative correlation between this variable and original sin, both if we control for single countries and for country groups. As stated in the paper, “ability to borrow abroad in one’s own currency seems to be heavily concentrated among large countries” (Eichengreen et al. 2003b: 5). Three relevant dimensions of country size are taken into account in the respective variable (SIZE) in the regression model: log of total GDP, log of total domestic credit valued in US dollars and log of total trade. A possible explanation of the robust correlation between country size and original sin can be found focusing on the role played by economies of scale or network externalities in shaping the structure of international finance. Furthermore, these findings suggest
Revista de Economia, v. 40, n. 72, p. 134-175, 2019 Gallo, Góes e Moraes 142
that the “redemption” from original sin can only be regional or international, aiming to a modification of the structure of the international monetary and financial system. This point will be crucial in the discussion of possible alternatives for Latin America in Section 4, after having evaluated the dimension of the phenomenon in the area.
2.4 The ‘Original Sin hypothesis’ in Latin America Latin American markets, particularly since late 1980’s, were subjected to a great influx of capital – so-called money chasing yield – motivated by low growth and low-interest rates in developed countries (external perspective) and by the implementation of political reforms inspired by the Washington Consensus (domestic perspective). Despite this good behaviour and the adoption of IMF recommendation, Latin American countries have been strongly hit by the reversion movement of the capital flows. Subject to the condition of ‘original sin’, the economy of these countries has faced extreme volatility of output and capital flows. A first answer to ‘original sin’ in Latin American countries during last decades was to abandon the national currency, adopting the currency in which debt is denominated (i.e. dollarization); that is still the case of countries like Ecuador, El Salvador and Argentina. As highlighted by Fritz and Metzger, when the option is the unilateral dollarization, the function of lender of last resort simply disappears and all debt is transformed into foreign currency. An alternative to dollarization – discussed in Section 4 – is monetary cooperation in form of an Optimal Currency Area (OCA)8. Facing such a big constraint to stabilization and, in its turn, development, in next sections our main aim is to ask the question of whether, after the turbulence of the 1990s, Latin American countries have reached any kind of ‘redemption to original sin’ (Hausmann and Panizza 2011). In Section 3, our empirical analysis will be based on the index OSIN3, as developed by Haussmann and Panizza (2003), that focuses on the international component of the original sin, as pointed
8 The difference between the two alternatives is highlighted by Cardim de Carvalho (2006, p. 104): “Dollarization, by contrast to the creation of an OCA, is the unilateral acceptance of the US dollar as the national currency by another country. It is not really monetary unification, since the rules of the game as to issuance of money, seigniorage gains, lender-of-last-resort facilities, etc., do not change with dollarization, since the United States does not in fact accept any responsibility for the decisions of other countries.”

out in Panizza (2006). The index will be calculated for the following countries: Argentina, Brazil, Chile, Colombia, Mexico, Venezuela; later on, we will analyse how the data behave throughout the time framework chosen.
3. Empirical assessment on ‘Original Sin’ in Latin America 3.1 Methodology and measures of ‘Original Sin’ As commented above, Eichengreen, Hausmann and Panizza (2002) created some indicators in order to investigate whatever a country is affected by ‘original sin’ or not. The authors present a vast literature about this topic, including several other indexes and forms of calculations and interpretations of ‘original sin’. For sake of simplicity, we opted to choose what is known in the literature as the best index for ‘original sin’. Additionally, we have chosen just to analyse the international side of ‘original sin’. Thus, the authors start by the indicator below:
